The “ISX” in Cummins ISX stands for “Interact System” which is the on-highway fuel system Cummins developed to vastly improve performance. Cummins ISX Engines are a very popular for on-highway and commercial trucking applications having the ability to pull between 430hp – 620hp at 2050 ft/lbs. Consequently, the brother of the Cummins ISX is the Cummins QSK which is part of the “Quantum” series. The Cummins QSX engine is the primary workhorse for off-highway, industrial, marine, heavy equipment and oil & gas applications. The Cummins QSX delivers between 365hp – 665hp at 1875 ft/lbs. of torque. We have the ability to do both Cummins ISX and Cummins QSX engine rebuilds.
Cummins ISX Fuel System
The Cummins 15L ISX is the latest engine in the ISX family which debuted in 2013. With the ISX 15 the fuel efficiency is increased 10%+ over previous models. The foundation of the ISX 15L is the reduction of the size of the radiator and multiple cooling panels. This reduction in size of the cooling system without the loss of cooling power mean overall better aerodynamics within the engine. The new Cummins ISX engine cooling system allows for losses from the engine’s alternator and various other water pumps to be mitigated. The new technology also allows for more open room which creates cooled air for the engine. The new cooling technology will likely save around 2,000 gallons of fuel per year for a class 8 truck which also means less particulate emissions. In addition to improved efficiency of the cooling system Cummins has also refined the combustion chamber to provide fewer active re-generations of the after treatment system.
The Cummins 15L ISX engine is the newest engine with the improved fuel system. Up until 2010 the traditional Cummins ISX engine featured the antiquated dual overhead camshaft design. One of the camshafts activated the injectors and the other camshaft activated the valve train. This type of injection system is called high pressure injection and operates to create injection pressure by the camshaft actuation. The dual cam design uses an integrated fuel system model (IFSM) which contains pressure regulators, gear pump, lift pump, metering and timing actuators and shutoff valve to accurately deliver diesel fuel directly to the injectors. The IFSM typically has a one section valve cover that is either plastic or chrome plated on older models of the Cummins ISX.

The latest versions of the Cummins ISX15 Engine keeping getting more fuel efficient as the technology keeps advancing. Cummins has stated that the newest ISX15 can deliver up to 2% better fuel economy than previously thought. The newest Cummins ISX15 operational efficiency actually delivers more horsepower than in older ISX Engine models.
The ratings on the ISX15 range from 400-600 hp (298-447 kW) with 2050 lb-ft of peak torque. The SmartTorque system Cummins developed adds roughly 200 lb-ft of extra torque to the top two gears of the engine. This means that Class 8 trucks can drive up steeper grades with much fewer downshifts making the ride that much smoother and less strenuous on the engine. For other models of the Cummins ISX engine the additional torque from the SmartTorque system is applied to the lower gears where it is needed the most. Capital Reman Exchange can provide a remanufactured Cummins ISX15 for half the cost of a new model without loss of efficiency or horsepower.

Cummins ISX Fuel Efficiency Physics
The fuel efficiency technology of the Cummins ISX Engine uses the power of steam. Harnessing the power of steam for propulsion purposes has been around for almost 2000 years. The steam engine was first patented in 1606 by Spanish inventor Jerónimo de Ayanz y Beaumont It was in 1698 that Thomas Savery patented a steam pump which condensed steam to create a vacuum to draw water into the chamber, then applied the pressurized steam to further a piston. The same basic steam technology is used today in the Cummins ISX. This scientific process is called the Organic Rankine Cycle.
Applying the Organic Rankine Cycle (ORC) to the diesel engine is quite a different process. Heat in a standard reciprocating engine if often looked as something to be avoided at all costs but with new technology it is utilized to aid in better fuel efficiency. The technology is called Exhaust Gas Recirculation (EGR) which turns excess heat from a major problem into the key to improved efficiency. In the Cummins ISX Engine the heat comes out of the engine and travels directly to a superheater system. The superheater increases the temperature of the wet steam from the boiler into an extremely dry superheated steam.
This concept of “dry steam” is steam that is heated beyond boiling. The dry steam contains a lot of energy which then turns a turbine in power plant systems. The turbine then turns a generator which converts waste heat into electricity. In the Cummins ISX engine the electricity is used to power a small electric motor built into the crankshaft. After the superheated dry steam’s energy is transferred into the turbine it later is sent to a recuperator then to a condenser where it is condensed and routed back into the boiler producing a closed loop system. This is quite a revolutionary concept for the Cummins ISX having both the internal and external combustion in one engine.
The extra energy that is recovered comes from four different sources: 6% increase in energy will come from the EGR, 2% will come from exhaust energy, and 2% will come from other accessories that used to drain additional power. All of this additional energy adds up to about 10% increase in overall fuel efficiency for the Cummins ISX 15.
The basic premise of the Cummins ISX Engine’s fuel efficiency is recovering waste energy. Waste energy can be described as energy that is not used for any practical purposes. Energy can be neither created nor destroyed just possess the form of kinetic energy (in motion) or potential energy (stored energy). When studying energy within the Cummins ISX Engine we can ascertain that most of the energy is stored in the diesel fuel as potential energy. When that diesel fuel is burned in the combustion engine it changes form to kinetic energy which then drives the pistons. However, most of the diesel fuel’s energy is lost as heat.
One gallon of diesel fuel contains about 139,000 Btu (British Thermal Unit) of potential energy. One Btu is defined as the amount of heat required to increase one pound of water one degree Fahrenheit. The goal with any engine is to achieve peak thermal efficiency where as peak thermal efficiency is described as the work you get divided by the energy you put in. For example a gas powered car engine is roughly 25% efficient and a heavy-duty diesel powered Cummins ISX engine is roughly 40% efficient. What that means is that if a vehicle used 10 gallons of gas only 4 gallons would go to towards propelling the tires forward; the other 6 gallons are wasted. The Organic Rankine Cycle technology in the Cummins ISX 15 aims to recovery as much energy as possible through heat recovery. Across the board, only roughly 33% of energy is used towards moving the motor.
An example of waste energy in relation to trucks is when heat escapes from the engine to the outdoors. The heat sources on a Cummins vehicle that help warm you up on a cold day include the Cummins ISX engine itself, the radiator, transfer case, transmission, differentials, U-Joints, brakes, cooling units, and your heater. Noise is also a heat source and is mostly a waste energy by product.
The second kind of energy is work energy. Work energy is harnessed energy being directed where you want it to go. However, there are always going to be other hindrances to 100% thermal efficiency. Gravity, inertia, laws of aerodynamics and drag will always be barriers to overcome to capturing 100% of an energy source. The second law of thermodynamics states that achieving 100% thermal efficiency can’t be accomplished.
ISX Emissions History
Cummins Isx Rocker Arm Torque
Cummins has always been on the forefront of emissions reduction and the development of technology that improves emissions output. The first technology Cummins introduced to help reduce particulate emissions was cooled exhaust gas recirculation or EGR system. This system was introduced in the Cummins ISX CM870 model in 2002 and works by taking exhaust gas and re-circulates it back into the engine intake. This process in turn radically lowers the combustion chamber temperatures in the Cummins ISX engine thus reducing the creation of Nitrogen Oxide. NOx and NOy (NOx plus other compounds that are created during the oxidation process of NOx) are the common causes of air pollution, smog and acid rain.
2013 Cummins Isx Engine Problems
Another big change in emissions reduction rolled out in 2008 when Cummins introduced Diesel Particulate Filter technology for the Cummins ISX CM871 model. Diesel Particulate Filter technology or DPF is a filtration system designed to trap particulate NOx matter created by the Cummins ISX engine. The second step of the system is the Diesel Oxidation Catalyst which further breaks down the particulate matter via oxidation of the ash. The ash of the diesel particulate is oftentimes called soot.

Then again in 2010 the Cummins ISX engine made another upgrade to its emissions technology with the ISX15 CM2250 model. The Cummins ISX15 CM2250 features the improved Exhaust Gas Recirculation in addition to Selective Catalytic Reduction for diesel particulate matter. These new guidelines further confined to EPA regulations also known as Urea Injection Reduction. The selective catalytic reduction system contains a diesel exhaust fluid composed of urea and water, controller, holding tank, pump, injector and the catalyst brick.
The system works by heating up the diesel exhaust fluid which is then pumped and injected into a decomposition area which then chemically reacts with the diesel exhaust in the Selective Catalytic Reduction chamber to reduce the level of NOx. The Cummins ISX15 uses one camshaft compared to previous versions which used two. This single camshaft design in the Cummins ISX Engine is due to the introduction of the common rail fueling system in which diesel fuel is pressurized from already high pressure. The fuel is stored in multiple piston pumps and transferred through tubes to a rail where the diesel fuel is stored under extremely high pressures up to but not including 35,000 psi.
